The Feasibility of Applying Space Syntax to Measuring Road Hierarchy
作者 鄭屹翔李子璋
中文摘要
本研究之目的為應用空間型構指標,建立系統性道路層級辨識程序,對於實際路網進行實證。現今的規劃中,偏向以交通工程的面向來判定道路層級,常用的指標如路寬、流量等;本研究試圖從路網構型的面向切入,以路段在路網結構中的連接重要性作為分級依據。本研究以空間型構法則之軸線分析作為量測工具,以不同的路網規模、量測半徑、軸線類型、量測指標作為測試參數,構成24種參數組合,再以英國米爾頓凱恩斯之路網系統為基礎製作路網樣板,測試各組合在路網樣板的量測值,以瞭解各種組合在辨道路層級之優勢。量測結果再以臺南安平五期重劃區路網進行實證分析,呈現良好之辨識結果,並能突顯少數連貫性過高之低層級道路,以及加入外部路網權重對判斷高層級道路聯外機能之效果。本研究之成果可作為後續研究參數及量測指標選擇之基礎,實務規劃上可作為判別路網連結合理性之工具。
英文摘要
The purpose of this study is to apply the space syntax method, establish a systematic road hierarchy identification program, and demonstrate its application on an actual road network. In current planning practices, road hierarchy is often determined based on traffic engineering perspectives, using indicators such as road width and traffic flow. However, this study takes a different approach by categorizing roads based on connections between road segments. To achieve this, the axial analysis of space syntax is used as a measurement tool. In order to evaluate the effectiveness of the proposed approach, various test parameters are considered, including road network scales, measurement radii, axial line types, and measurement indicators. This leads to the formation of 24 parameter combinations, which are subsequently tested on a road network model based on the road network of Milton Keynes, UK. The objective is to understand how each combination performs in identifying road levels. The testing results are then analyzed empirically using the road network of the Phase 5 Readjustment Area in Anping, Tainan, which provides valuable insights. Specifically, the analysis successfully highlights low-level roads with high coherence and explores the effect of adding external weights in determining high-level roads. These results serve as a foundation for the selecting parameters and measurement indicators in subsequent research and offer a practical tool for evaluating the rationality of road network connections in planning processes.
